2 Claims.

Another object is to hold the sheathin against the studding underslightly yielding tens on and thereby allowing for expansion andcontraction, settlingof the building, etc.

A further object is to provide a more econom- 15 ical and durable meansof attaching sheathing panels to the studding or other support in theerection of the modern low cost building.

Further objects are to provide a construction of maximum simplicity,efficiency, economy, case 20 of assembly and operation and such furtherobjects, advantages and capabilities as will later more fully appear andare inherently possessed thereby.

The invention further resides in the combina- 15 tion, construction andarrangement of parts illustrated in the accompanying drawing and whilewe have shown therein a preferred embodiment it is to be understood thatthe same is susceptible to modification and change without departing 30from the spirit of our invention.

In the drawing! 1 is a fragmentary perspective view of a portion of awall and studding member with the fastening means in place.

35 Fig. 2 is a cross sectional view showing more clearly the insertionand application of the fastening means.

Fig. 3 is a view of one of the spiral or corkscrew members of thefastening means.

Fig. 4 is a view of the clip bridging the two spiral or corkscrew"members.

Fig. 5 is a modified form of one of the spiral or corkscrew members ofthe fastening means.

Fig. 6 is a fragmentary cross sectional view 45 showing the applicationof the modified form of fastening means.

Referring more particularly to the disclosure in the drawing Fig. 1shows a panel of sheathing l of hard fireproof material. This may be as-50 bestos cement or other suitable material and is very rigid and highlycompressed with little porosity. On one side of the outer sheathing l isa layer of insulating material 2, attached to the sheathing l bywaterproof glue and weatherproof mastic. This sheathing and insulatingmaterial are manufactured by a. number of companies and may be securedin the market.

The panel of sheathing and insulating material are placed against astudding 3 with the in sulating material on the inside.

Our preferred form of attaching means comprises a clip 4 having eyelets5 at each end. This clip 4 is placed through a portion of the studding10 3. Thereupon corkscrew member 6, provided with a head I longer thanthe eyelet 5, is inserted through eyelet 5 of the clip and then screwedinto the insulating material 2 until the clip is under'yielding tensionand has bent as shown in Figs. 1 and 2.

We have shown in Figs. 5 and 6 a modified form of clip and corkscrew.The modified form of corkscrew 8 has a bent head 9. When using thismodified form the corkscrews 8 are screwed in place on opposite sides ofthe studding 3 and the clip I0 is then forced into holding engagementwith the hooked portion of the head 9, as

shown in Fig. 6.

In order to center the clip at the studding a bend H is provided whichprevents the clip from sliding in its tensional engagement with the head9 of the corkscrews.

Experiments and tests have been shown that with this invention thesheathing is held more securely than by other methods, such as nailingto the studding and providesagainst cracking and other unsatisfactoryresults of settling of the building.

Having thus described our invention, whatwe claim as new and desire tosecure by Letters Patent is' I 1. Fastening means for securing panels tostudding or other support comprising a yieldable clip adapted to engagethe studding at a point 40 intermediate the ends of the clip, andhelical members adapted to detachably engage the opposite ends of theclip in adjustable relation thereto and secured to said panels.

2. Means for holding sheathing panels to stud supports under yieldabletension comprising a spring wire clip adapted to engage a portion of thestud supports and a pair of helical members adapted to be screwed into aportion of the sheathing panels and yieldingly attached to the ends ofsaid clips.
